Thanks for the replies. I ended up adding a widget area to the header. It was significantly less difficult than I thought once I read through the code for the rest of the theme. And I like the level of control that the textbox widget offers. Now, all I have to do is remember that it is not a general-purpose widget area, and everything will be okay.

The widget approach is still looking best to me. But something like a static page makes a certain amount of sense as well.
